Key result
The 22-item CHD-PEBBS scale demonstrated good internal consistency (Cronbach's alpha 0.917) and test-retest reliability (0.941) for assessing perceived exercise benefits and barriers in CHD patients.
Why the study?
Perceived exercise benefits and barriers influence cardiac exercise rehabilitation, but validated tools assessing coronary heart disease patients' exercise perceptions were lacking.
Cross-Sectional (n=205)
Yes
The newly developed CHD-PEBBS is a reliable and valid tool for assessing perceived exercise benefits and barriers in patients with coronary heart disease, which can help tailor cardiac rehabilitation interventions.
CHD-PEBBS may support exercise perception assessment in CHD; leaves open effects on rehabilitation adherence or outcomes.
Background: The level of perceived exercise benefits and barriers is one of the key influencing factors of cardiac exercise rehabilitation (CER). There is a lack of validated tools to assess coronary heart disease (CHD) patients' exercise perception. Purpose: The aim of this study is to develop a scale assessing CHD patients' perceived exercise benefits and barriers (CHD-PEBBS) and test its reliability and validity. Methods: A total of 205 CHD patients were recruited for a cross-sectional survey. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to extract factors, delete items and evaluate construct validity. The Cronbach's alpha coefficient and test-retest reliability were used to test the reliability of the scale. Results: /df=2.281, CFI=0.93, RMSEA=0.079) were all acceptable A total of 6 factors were extracted through EFA, with a cumulative variance contribution rate of 75.52%. The perceived benefits subscale included 3 dimensions: "improving physiological indicators", "improving quality of life" and "improving physiological function" with a total of 12 items. The perceived barriers subscale also included 3 dimensions: "lacking of exercise support", "worrying about adverse consequences" and "poor exercise experience or perception" with a total of 10 items. The Cronbach's alpha coefficient of the scale was 0.917, and the test-retest reliability was 0.941. Conclusion: The CHD-PEBBS shows good reliability and validity, which may be used to evaluate the CER perception level of CHD patients, offering precise targets and pathways for exercise rehabilitation interventions in nursing.

Feng et al. (2025) conducted a cross-sectional in Coronary heart disease (n=205). CHD-PEBBS scale was evaluated on Scale reliability and validity. The 22-item CHD-PEBBS scale demonstrated good internal consistency (Cronbach's alpha 0.917) and test-retest reliability (0.941) for assessing perceived exercise benefits and barriers in CHD patients.
